Hydrotreating of triglyceride using SBA-15 mesoporous supported NiMo catalyst by micro waves in a fixed bed reactor
Résumé
Direct hydrogenation of triglycerides into alkanes constitutes an alternative route for the production of biofuels ofr diesel engines. In the present study, hydrogenation of a small triglyceride was performed in a continuous manner, using Micro Waves, and a sulphide catalyst. SBA-15 supported NiMo hydrotreating catalysts were prepared by incipient wetness impregnation method. NiMo/SBA-15 powder was extrudated with addition of boehmite (AlOOH) as binder. A monomode cavity has been designed to perform, under hydrogen pressure, in a continuous manner, the hydrotreating of triglyceride in a fixed bed reactor with extrudated NiMo/SBA-15 catalyst that was sulfided with 15 vol% of H2S before reaction.
